Book Description
Human activities are significantly modifying the natural global carbon (C) cycles, and concomitantly influence climate, ecosystems, and state and function of the Earth system. Ever increasing amounts of carbon dioxide (CO2) are added to the atmosphere by fossil fuel combustion but the biosphere is a potential C sink. Thus, a comprehensive understanding of C cycling in the biosphere is crucial for identifying and managing biospheric C sinks. Ecosystems with large C stocks which must be protected and sustainably managed are wetlands, peatlands, tropical rainforests, tropical savannas, grasslands, degraded/desertified lands, agricultural lands, and urban lands. However, land-based sinks require long-term management and a protection strategy because C stocks grow with a progressive improvement in ecosystem health.

Book Description
Quantify carbon stock on forest restauration areas is a global interest, since this area provide the important environmental service of mitigating climate change. It is crucial have more studies on allometry to help on predicting biomass and carbon stocking for those areas. Thus, the objective of this study was to quantify forest biomass and carbon content to a 5-year-old region under restoration process, so models could be fitted to the area and also used to similar sites. Three sites nearby Itu city, SP, Brazil, were studied, 5 years after the restoration process was implemented. In each site, three 900 mu00b2-plots were installed, and a forest inventory was done, measuring tree height and circumference at breast height. Sub-plots (25 m2) were randomly selected in each 900 m2-plots and all trees inside it were cut and had its volume measured, stratified into foliage, roots and stem pools. Carbon content was determined on the Isotopic Ecology Laboratory for each species and pool. This data was used to fit models to estimate biomass. The best model was selected using the adjusted coefficient of determination (Ru00b2), residual charts and Akaikeu2019s information criterion (AIC). Mean biomass for the area was 20.19u00b10.146 Mg hau207bu00b9, mean Carbon stock was 9.73 Mg C hau207bu00b9, and average carbon content was 45.3%.

Book Description
This paper explores opportunities for implementing activities for reducing emissions from deforestation and forest degradation (REDD) in areas with high poverty rates, rapid population growth and complex social dynamics. We focus on the potential role of localized Forest Management Units (or KPH) as an institutional partner, using the West Rinjani Protected Forest Management Unit (KPHL RB) on the island of Lombok, Nusa Tenggara Barat province, Indonesia as a case study. We relied on five essential elements for our analysis: (1) identification of land use changes, (2) estimation of average carbon stocks in forests and shrubland, (3) socioeconomic surveys to identify drivers of deforestation and forest degradation, (4) estimation of future reference emission levels, and (5) developing alternatives to reduce the rates of deforestation and forest degradation.

Book Description
Above ground biomass has been listed by the Intergovernmental Panel on Climate Change as one of the five most prominent, visible, and dynamic terrestrial carbon pools. The increased awareness of the impacts of climate change has seen a burgeoning need to consistently assess carbon stocks to combat carbon sequestration. An accurate estimation of carbon stocks and an understanding of the carbon sources and sinks can aid the improvement and accuracy of carbon flux models, an important pre-requisite of climate change impact projections. Based on 15 research topics, this book demonstrates the role of remote sensing in quantifying above ground biomass (forest, grass, woodlands) across varying spatial and temporal scales. The innovative application areas of the book include algorithm development and implementation, accuracy assessment, scaling issues (local–regional–global biomass mapping), and the integration of microwaves (i.e. LiDAR), along with optical sensors, forest biomass mapping, rangeland productivity and abundance (grass biomass, density, cover), bush encroachment biomass, and seasonal and long-term biomass monitoring.

Research Paper (undergraduate) from the year 2023 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: 3.63 (B+), language: English, abstract: This review presents a systematic review on the Biomass Carbon Stock Estimation Options for Trees and Forests Resources within and around Mago National Park, Southern Region of Ethiopia. In order to review and gain information from existing research on types of forest, basal area, biomass/carbon stock, sequestration pool in different forest ecosystems of Mago National Park, a literature research was carried out during January 2022 to October 2022 using Web of Science, Google Scholar Citation, Research Gate, IPCC, United Nations Framework Convention on Climate Change (UNFCCC) and REDD+ report, offline journals, book chapters, government scientific reports, Forest Survey data, Botanical Survey data, as well as reports published by Ministry of Environment, Forest and Climate Change. The review is limited to in and around Mago National Park forest ecosystem in relation to above and below biomass and carbon stock estimations. Formulating allometric equations for all woody plants in Ethiopia is quite desirable for accurately quantifying the biomass and carbon stock of forests to achieve accurate national and international reporting of carbon dioxide emission inventories. Depending on this in Ethiopia several studies undertaken regarding allometric equation for biomass estimation, but it is not as forest resource of the country. Most of the study undertaken was depend on semi-destructive method, which is not accurate as destructive measurement. Forests play an essential role as source and sink in the global carbon cycle. Development and other human induced activities have led to degradation of forest land, and ultimately, it results in loss of biodiversity and increases concentration of CO2 in atmosphere. Therefore, there is urgent need to estimate regional and national le

Book Description
Live tree biomass estimates are essential for carbon accounting, bioenergy feasibility studies, and other analyses. Several models are currently used for estimating tree biomass. Each of these incorporates different calculation methods that may significantly impact the estimates of total aboveground tree biomass, merchantable biomass, and carbon pools. Consequently, carbon markets, bioenergy projects, and similar efforts may be affected. In addition to differences in allometric equations, the various methods are most suitable for particular geographic scales of analysis. We examine three approaches that might be used for midscale analyses (e.g., 25,000 to several million acres) and compare the regional models with equations developed by Jenkins et al. and with the component ratio method (CRM). These three methods produce relatively similar estimates of total aboveground biomass for softwood species in Oregon, but substantially different estimates for the proportion of total biomass that is merchantable . For the major softwood species in Oregon, the total aboveground biomass using the CRM is 3 percent lower than estimates with regional equations, and the Jenkins models produce estimates that are 17 percent higher. However, on average, the proportion of softwood merchantable biomass computed with CRM is about 83 percent of the total aboveground biomass with little variation from species to species, whereas regional models estimate that 72 percent is merchantable, and the Jenkins equations estimate that 78 percent is merchantable.

Book Description
Forest ecosystems are important because of the key role in reducing atmospheric greenhouse gas concentrations by storing a large amount of carbon in biomass and soils. The relative amount of above-ground biomass allocated among different tree tissues is a functional indicator of forests’ health reflecting the material flow, the wood quality and the plant survival strategy. The way in which plants steer their photosynthetic product across their compartments is not fixed but likely vary over time, across growth economies and among species and, lastly, is influenced by plant size and climate, Obtaining a qualitative/quantitative understanding of the influence that these factors have in both growth and biomass allocation is of fundamental importance either in understanding plant ecology and evolution and into developing environmental policies and useful forest management practices to cope with future climate change.
